Uber India — I was charged extra toll price for my uber ride

Unnecessary toll charges were added to last uber ride i took.. The estimated price was 380 rs and i was charged 110 rs extra along with 8 rs as waiting fare, that is i paid 500 rs to the driver without reason. I want my refund back. There is no complain number or any source where i can register my complaint. I want this to be resolved as soon as possible.
